The different identity of an ethnic minority may be displayed in any number of ways, ranging from distinctive customs, lifestyles, language or accent, dress, and food preferences to particular attitudes, moral values, and economic or political beliefs espoused by members of the group.n unfortunate secondary characteristic of ethnic minority status is that it is often accompanied by prejudice and discrimination. Ethnic minorities tend to be at a disadvantage in most situations, most often because they are stigmatized as different from the norm.
In 1931, Dr. Warburg won a Noble Prize for proving that cancer is caused by a lack of oxygen into the cells. Since then, many similar studies have been done which agree totally with this discovery. The simple answer is to supply the cells with oxygen to handle the starvation which is the real cause.
Reduced oxygen levels (hypoxia) is one of the most important factors influencing clinical outcome after radiotherapy. This is primarily because hypoxic cells are resistant to radiation treatment; hence, the greater the number of clonogenic cancer stem cells that exist under hypoxia, the lower the local tumour control.umour hypoxia and radiotherapy. Hypoxia in tumours arises because the oxygen demands exceed the oxygen supply. The growth and development of solid tumours requires the formation of a functional vascular supply, which evolves from the normal host vascular network by the process of angiogenesis.
